CNN’s Jake Tapper cut off top White House adviser Stephen Miller on Sunday during a contentious interview on State of the Union.

Tapper accused Miller of “[wasting] enough of my viewers’ time” by slamming CNN’s coverage of the Trump White House instead of answering questions directly. “There’s one viewer that you care about right now and you’re being obsequious,” Tapper told Miller, referring to President Donald Trump. The sit-down centered mostly on the claims made by former White House chief strategist Steve Bannon in Michael Wolff’s new book, Fire and Fury. “It’s tragic and unfortunate that Steve would make these grotesque comments so out of touch with reality and obviously so vindictive,” Miller told Tapper, adding that Bannon’s role at the White House “has been greatly exaggerated.” The Daily Beast reported last year that Bannon’s allies in the White House, including Miller, were souring on him, and Miller said his “friendship with Steve is stronger than ever.” Trump reacted to the interview in a tweet later Sunday morning: “Jake Tapper of Fake News CNN just got destroyed in his interview with Stephen Miller of the Trump Administration. Watch the hatred and unfairness of this CNN flunky!”
